I'm struggling to figure out how to begin. I would like to us a teensy 3.2 to monitor the can bus on a GM vehicle to capture when the car is in reverse, and capture the steering when buttons for phone and media control. I want to integrate this with openauto pro. I would like the teensy simply to listen to the gmlan, and when one of the buttons is pressed or reverse is entered, the teensy would simple send usb key code to raspberry pi based on what message it sees.
But I am having difficulty with how to listen for this info on the can bus. Is there anyone who has done something like this or can point me to how to read these messages from the bus?
